PIPE-RACK 'Darrin-CAR.

To all whom may concern.'

Be it known that I, JAMES I. MARTIN, a citizen of the United States, andresident of Lancaster, inthe county of Lancaster and State ofPennsylvania, rhave invented an Improvement in Pipe-RackDrier-Cars, ofwhich the following description, in connection with-the accompanyingdrawings, is a specification, like letters on the drawings representinglike parts.

My present invention is an improved apparatus consisting in a multipleunit pipe rack drier car, intended primarily for use in the drier systemillustrated and explained in my copending application, Ser.4 No.194,640, file-d Gctober 4, 1917;

In the manufacture of clay products, particularly brick, it is necessaryto first dry the brick and then to burn the same in kilns of varioustypes'. The best type of drier heretofore known'has been the steam piperack driers, which required large, expensive, permanently builtstructures with a vast amount of steam pipes forming racks,- on whichracks the Vindividual brick units had to be placed, either by handor onshort pallets containing five or six brick units, which latter had to bepositioned by hand. The constant handling 4'in the necessary use of sucha steam pipe rack drier, both loading and unloadingV by hand, andthelarge plant and building necessary, has been a serious diiiiculty inusing this type of drier. My present invention obviates the formerdifficulties of such steam pipe driers while utilizing all theadvantages incident thereto, and providing a movable drier unit, whichcould be advantageously employed in a car, and used in a wasteheatdrier, a tunnel drier, railroad kiln drier, or the like.

My pipe rack drying truck or car combines in an ideal manner thenumerous addling clay products, directly from the brick making machineto a drier, each car being capable of independent connection with asource of steam supply or of being connected to each other, in a train,either' of a few cars; or of being connected in a continuous train, suchas in a tunnel drier, said cars being thereafter delivered to the kilnshed for burning. My novel idea of a steam pipe rack drying car enablesthe novel arrangement of my said copending application in an entiremanufacturing l Specification of Letters Patent.`

plant, and as the individual pipe rack car is an important feature ofsaidsystem and a distinct novelty, I wish to claimV the same broadly. Y

Referring to. the drawings, illustrating a preferred embodiment of myinvention,l

vFigure 1 is a plan view of the car;

Fig. 2 is a side view; and

Fig. 3 an end.v

As shown in the drawings, mv individual drier car consists in aplurality .of pipe shelves adapted to receive the pallets containing thebrick to be dried; The car herein shown is of sufficient width toreceive pallets of brick from each side, the pipe being arranged inshelf sections at each side of the car. The car consists in a `pair ofbottom frames 1 and 2, preferably iron I- beams, having cross beams 3and 4 adjacent either end, which frame has sets of journal bearings 5,5, to carry the axles 6 for the car wheels 7 7'. The bottom of the frameVis preferably open, although the cross brace 8 may be provided withreinforcing straps 9, 9. Upon the frame, at either end, is an luprightbrace, that shown at 10 being relatively heavy' and bolted to the lowerframework, carrying the steam pipe manifolds 11 and 12; at the other orexpansion end of the car is the upright brace 13, which preferably isreinforced by straps 14 .downwardly to the projecting ends of the I-beams 1 and 2. Across the top of the car are straps 15', 15,' and sidebraces 16, 16, giving a firm, strong, open framework. The upright braces10 and 13 are perforated, the upright 13 having a plurality of pairs ofperforations or openings, as illustrated at 14, 14, and 16, 16, thesebeing substantially in tiers at either side of the car, as clearly shownin Fig 3; Through these openings the ends of the steam pipes 20, 20,project, short elbows 21, connecting each pair of pipes with a suitablepiece 22 of appropriate length, all being threaded together, as iscustomary. At the manifold end of the car, a single set of perforations,as shown at 23 and 24, are provided, the vertical manifold pipes 11 and12 being threaded to receivevthe respective ends of the outer pipes inthe drier. Either a manifold 11 or 12 can be utilized as for thereceiving or incoming steam, while the other will be for the outlet,both receiving and outlet connections being thus made at the same endtier, from the manifold ll toward the expansion end, around through theelbow 2l and vshort connecting pipes 22 through the adjacent elbow 22and the parallel section of pipe backwardly to the manifold end, andthen return to the expansion end and backwardly to the outlet manifoldl2. The expansion of each pipe 20 is readily taken up Y by the -slidablemovement promoted between the pipe 20 and the recesses therefor in therack 31, without undue strain, without binding, or other difficulty, andwithout inV any way loosening the steam pipe joint in the elbows 2l. Thecar can be'run in adjacent the dump table by the brick making machine,the steel pallet with its load of brick slid onto the shelves formed bythe pipes 20, until the car is full, then the car is wheeled o n to thedrier, steam pipe connected, and drying completed, whereupon the steamVpipe is disconnected and the car wheeled to the kiln where the brick arestacked for burning.

When it is appreciated that in steam pipe driers, as heretoforeconstructed, long permanent buildings were required, with permanentsupports for the piping, and separate conveyers to take the brick fromthe dump table to the different points throughout the drier, andaconstant hand labor both at dump table, conveyer and drier,

both when loading and unloading, the importance of my invention will bemanifest. Furthermore, my car can be lutilized fin ay tunnel drier,conserving heat, reducing labor to a minimum, preserving a continuoussystem or method of operation, and standardizing brick manufacture.

My invention is further described and defined in the form of claims asfollows:

l. A multiple pipe rack drier car of the kind described, comprising atruck, a plurality of horizontally arranged steam'pipeY racks, formingshelves, each rack comprising a plurality of pipes, a verticallyextending manifold for said pipes at one end of the car, meanspermitting independent expansion and contraction for the pipes formingeach shelf,` and Isupply and exhaust means for the circulation of steamthrough the pipes in each rack.

2. A multiple pipe rack drier car yof the kind described, comprising atruck, a plurality of horizontally arranged steam pipe racks, each rackcomprising a plurality of pipes, a vertically extending manifold forsaid pipes at one end of the car, a support at the other end of the carfor said pipes, permitting independent expansion and contraction for thepipe in eachshelf, and supply and exhaust means for the circulation ofsteam through all the pipesin every rack.

3. A multiple pipe rack drier car of the kind described, comprising atruck, a plurality of horizontally arranged steampipe racks, supportsfor said lracks permitting expansion and contraction of the piping ineach rack, and vertically extending supply and exhaust manifoldsadjacent one end of the truck to provide forv the circulation: of steamthrough all the piping in each rack.

In testimony whereof I haveYV signed my name to this specification. :l-
